SIDEWALK, FLOOR, VAULT, AND ROOF LIGHT CONSTRUCTION.

Application filed June 12, 1911, Serial No. 632,549.

To all 1071-0972, it may concern:

Be it known that I, LOGAN WILLARD Mon Form, a citizen of the UnitedStates, residing at Narberth, Montgomery county, State of Pennsylvania,have invented a new and useful Sidewalk, Floor, Vault, and Root LightConstruction, of which the following is a specification.

My present invent-ion relates to sidewalk, floor, vault and roofiightconstruction, and one-of the main objects of my present invention is todevise a construction which may be installed by unskilled labor andwhich may be shipped from the factory in a knocked-down or disassembledcondition,

thereby enabling me to ship the stock material, such as iron or otherbars or plates, either loose or tied in bundles so that after the partsare received at the place of installation they may be assembled by theemployment of unskilled labor, the lenses placed in position and thebinding material placed between the lenses, whereby both the cost oftransportation, the cost of erection and thus the entire cost ofproducing the construction is materially reduced without affecting inany manner the strength and artistic finish of the completedconstruction.

My invention further consists of a novel sidewalk, floor, vault androof-light construction wherein I provide novel means for forming anincreased thickness of the rib of cement between the lenses.

It further consists of novel means for forming an expansible joint whichwill pre vent any leakage of fluid through the con struction.

It further consists of a novel construction of a lens supporting plate,which is assembled in a novel manner with respect to the rest of theconstruction.

It further consists of other novel features of construction, all as willbe herein Specification of Letters Patent.

RenewedJanuary 4, 1913. Serial No. 740,239.

rangement and organization of these instrumentalities as herein shownand described. Figure 1 represents a perspective view of a portion of acompleted and partly completed sidewalk, floor, vault and roof-lightconstruction embodying my invention. Fig. 2 represents a sectionalelevation of a portion of Fig. 1. Fig. 3 represents a sectionalelevation of Fig. 1, taken at right angles with the section seen in Fig.2. Fig. 4: represents a perspective view of another embodiment of myinvention. Fig. 5 represents a sectional elevation of Fig. 4:.

Similar numerals of reference indicate corresponding parts in thefigures.

I have preferred to show the primary spacing bars 1, in the presentinstance, as consisting of an inverted T-shaped bar,'the upwardlyextending web 2 of which is provided with recesses or slots 3 which, inthe present instance, are V-shaped in order to form seats, it beingunderstood that the primary spacing devices 1 are adapted to besupported in any desired manner, such as for example on abutments 4:, inthe vault, room, or building where my novel construction is to beinstalled. The notches or recesses 3 are located at any desired distancefrom each other and are adapted to receive the transversely extendingsupporting bars 5, which, in the present instance, for the sake ofillustration, have been shown as V shaped in order to engage therecesses 3.

6 designates strips or plates of metal, or other desired material, whichare seated on the upper face of the transversely extending supportingbars 5 and provided at opposite edges with the downwardly deflectedporversely extending bars 5, it being understood that in thisembodiment, the extensions or deflected portions 7 preferably do notextend to the bottom of the V-shaped bars 5.

8 designates apertures of any desired contour in the plates 6 and theseapertures are adapted to be covered by lenses 9 which may be of anydesired or conventional form, as will be clearly apparent from Fig. 1.

In the embodiment seen in Figs. 1 to 3 inclusive, two adjacentparallelly arranged secondary bars 5 support one of the plates 6- whichis longitudinally adjustable thereon and which may extend any desireddistance and serves as a support and spacing device for the lens and asa support for the binding material 10, it being noted from Figs. 1 and 2that the binding material 10 extends below the lower ends of theextension 7, as indicated at 11, which binds the secondary bars 5relatively to the plate members 6. In case a round lens is employed, thesame preferably is provided with a lower rib 12 which is adapted. toseat on the plate 6 and also provided with one or more ribs 18 whichinterlock with the concrete 10. If a square lens is employed, the samepreferably is provided with one or more ribs 1a which interlock with theconcrete 10, while the lower portion is provided with a laterallyextending flange 15 which is seated on the plate 6, and with lower lugsor foot flanges 16 which pass through an aperture 8 whereby the lensesare properly spaced relatively to each other. i In the embodiment seenin Figs. at and 5, I have shown another embodiment of my inventionwherein, instead of using a series of plates 6, I employ a continuousplate 17 which is provided with lens receiving aper tures 18 which maybe of any desired contour, said plates 17 having the V shapeddepressions 19 therein which are adapted to seat in and interlock withthe V -shaped bars 5 in order to prevent any improper relative movementof the parts, it being noted that in this construction the bindingmaterial 10 is wholly supported by the plate 17.

Special attention is directed to the novel expansible joint which Iprovide, whereby the leakage of water through the construction ispositively prevented. At desired dis tances apart throughout theconstruction, I provide a waterproof composition 20 which is seated inthe V or other shaped groove 21, said groove being located in alinementwith the secondary bars 5 which, in the present instance, for thepurpose of illustration, I have shown as having a contour of a Valthough as will be apparent any desired form of secondary bar may beemployed. The groove or slot 21 terminates a desired distance from thebottom of the bar 5 but preferably extends beneath the upper surfacethereof, thereby providing for the expansion and contraction of thematerials without affecting the solidity of the completed construction.It will be evident that if any liquid should leak into the groove 21,which in practice is opened at its lower end due to the expansion andcontraction of the concrete, such liquid will be retained within thechamber of the secondary bar 5 or in the embodiment seen in Figs. 4 and5 will be re tained in the chamber formed by the deflected portion 19 sothat such liquid is prevented from passing through the construction.

hen it is desired to install my novel device, the primary spacing bars 1are located on suitable abutments at desired distances apart inaccordance with the load which they are designed to carry, the secondarybars are then placed in position so as to interlock with the seats 3 inthe primary bars 1. The plates 6 are then placed in position so thatthey will be seated on the upper face of one of the angles of one of thebars 5 and the deflected portions 7 will engage th side of one of theangles of the bars 5, so as to interlock therewith. The lenses are thenplaced in position so as to cover the aoertures 8 and be seated on theplates 6, it being noted that the lenses are carried and spaced by thelens supporting plates. The binding material, such, as for example,cement or concrete, is then filled in between the lenses to the levelthereof, so that the binding material will secure the lenses in positionand will also extend into the recess or chamber of the bars 5 in such amanner that portions 7 of the plates 6 will be covered by the bindingmaterial and also the bars 5, and a bond will be formed between suchplates and the bars 5.

In the embodiment seen in Figs. 4 and 5, it will be seen that the partsare assembled in a similar manner except that the lenses and cementsupported on the plate 17, is adapted to extend over a plurality of thelaterally extending bars 5 and is deflected in such a manner as tointerlock with the secondary bars, it being noted that in thisembodiment, the same as in the embodimentseen in Figs. 1 to 3 inclusive,there is no likelihood of the concrete passing through the constructionor between the plates and the supporting bars.

In my present d vice, as in my allowed application to which I havehereinbefore referred, the bars employed may be cut the desired lengthsat the factory and then shipped in bundles, with the lenses and theapertured plates, from the factory to the place of installation, atwhich the same may be assembled and the construction completed byunskilled labor.

In so far as I am aware, I am the first in the art to devise a sidewalk,floor. vault and roof-light construction provided with an expansiblejoint wherein an underlying bar will coeperate therewith to positivelyprevent any leakage through the joint from passing through theconstruction, and it is to be understood that my claims to such featuresare to be interpreted with corresponding scope. I am also the first inthe art, in so far as I am aware, to devise a con struction wherein aplate of material having lens receiving apertures therein is provided,which is adapted to support and space the lenses and support the bindingmaterial,

.and which is provided with depressions extending below the walls of theapertures in order to form an increased thickness of the bindingmaterial betweenthe lenses. It will further be apparent that in thebroad scope of my invention, the primary bars 1 and the secondary bars 5may have any desired contour given thereto and are not limited to thetype shown for the purpose of illustrating one embodiment thereof. Itwill also be seen that my device when assembled and completed isprotected against the injurious effects of expansion and contraction dueto variations of temperature, owing to the novel manner in which theparts cooperate and that my novel construction is also protected againstleakage at all points, and I am enabled to produce a surface of anydesired length. Special attention is also directed to the fact that inmy novel construction the lens supporting plates are longitudinallyadjustable relatively to the secondary bars, and these plates may bewholly supported on the secondary bars or if desired they may alsoengage with the primary bars as is evident.

It will now be apparent that I have devised a novel and usefulconstruction of a sidewalk, floor, vault and roof-light which embodiesthe features of advantage enumerated as desirable in the statement ofthe invention and the above description, and while I have, in thepresent instance, shown and described a preferred embodiment thereofwhich has been found in practice to give tages.
